N. T. Wright argues that each of these questions takes us into the mystery of who God is and what he wants from us. For two thousand years Christianity has claimed to answer these mysteries, and this renowned biblical scholar and Anglican bishop shows that it still does today.

Like C. S. Lewis did in his classic Mere Christianity, Wright makes the case for Christian faith from the ground up, assuming that the reader is starting from ground zero with no predisposition to and perhaps even some negativity toward religion in general and Christianity in particular. His goal is to describe Christianity in as simple and accessible, yet hopefully attractive and exciting, a way as possible, both to say to outsides "You might want to look at this further," and to say to insiders "You may not have quite understood this bit clearly yet."
